DETAILED DESCRIPTION OF THE EMBODIMENTS

(11) In order to make those skilled in the art better understand the technical solutions of the present invention, a cloth taking-up device according to the invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

First Embodiment

(12) As shown in FIGS. 2-4, this embodiment provides a cloth taking-up device, including: a platform 1, on which glue to be taken-up 3 and cloth to be taken-up 4 are disposed; and a clamp part 2 movable with respect to the platform 1, which is configured to clamp a roller 5 and roll the glue to be taken-up 3 and cloth to be taken-up 4 successively onto a surface of the roller 5. An outside surface of the platform 1 may have an included angle of 0-180 with respect to the horizontal plane, the glue to be taken-up 3 and the cloth to be taken-up 4 are disposed on the outside surface of the platform 1, and the clamp part 2 is capable of keeping the roller 5 in parallel with the outside surface.

(13) By laying the glue to be taken-up 3 and the cloth to be taken-up 4 onto the outside surface of the platform 1 having the included angle of 0-180 with respect to the horizontal plane and keeping the rollers 5 in parallel with the outside surface, the glue to be taken-up 3 and the cloth to be taken-up 4 can be rolled onto roller surfaces of the rollers 5 in a lateral-press manner, whereby avoiding uneven pressure applied to the glue to be taken-up 3 and the cloth to be taken-up 4 by rollers in the case of taking up glue and cloth in the down-press manner, and in turn improving uniformity of taken-up glue/cloth. Meanwhile, cloth/glue dropped off situation may not occur in the finished rollers 5, thereby ensuring the rubbing quality of the rollers 5 in a process of the rubbing formed alignment layer. Since the glue to be taken-up 3 and the cloth to be taken-up 4 are situated in a non-horizontal position, the foreign matters on the glue to be taken-up 3 and the cloth to be taken-up 4 can easily fall off, and the foreign matters on the rollers cannot drop onto the glue to be taken-up 3 and the cloth to be taken-up 4 with the rotation, thereby ensuring glue/cloth taking-up quality.

(14) In this embodiment, as shown in FIGS. 2-4, the platform 1 may be of a rectangular parallelepiped shape, and the outside surfaces of the platform 1 may include a first side surface 11 and a second side surface 12 which are oppositely arranged. The first side surface 11 and the second side surface 12 are in parallel with each other and perpendicular to the horizontal plane. The glue to be taken-up 3 and the cloth to be taken-up 4 are laid on each of the first side surface 11 and the second side surface 12. In such an arrangement, it is possible to further improve the uniformity of pressure applied to the glue to be taken-up 3 and the cloth to be taken-up 4 by the rollers 5, such that the glue and the cloth can be uniformly laid on the rollers 5, avoiding the cloth/glue dropped off situation. Meanwhile, it is easy for the first side surface 11 and the second side surface 12 perpendicular to the horizontal plane to make the foreign matters on the glue to be taken-up 3 and the cloth to be taken-up 4 drop off. In addition, since the rollers 5 is in parallel with the first side surface 11 and the second side surface 12, it is possible to avoid the foreign particles on the rollers 5 from dropping onto the glue to be taken-up 3 and the cloth to be taken-up 4 with the rotation, thereby further ensuring glue/cloth taking-up quality

(15) In this embodiment, one piece of glue to be taken-up 3 and one piece of cloth to be taken-up 4 are laid on each of the first side surface 11 and the second side surface 12. However, it should be noted that, according to areas and practice demands of the first side surface 11 and the second side surface 12, pieces of glue to be taken-up 3 and pieces of cloth to be taken-up 4 may be laid on each of the first side surface 11 and the second side surface 12.

(16) The clamp part 2 includes a first clamp mechanism 21, a second clamp mechanism 22 and a driving mechanism 23. The first clamp mechanism 21 and the second clamp mechanism 22 are connected to the driving mechanism 23, respectively. The first clamp mechanism 21 and the second clamp mechanism 22 are provided in pair, and disposed on the third side surface 13 and the fourth side surface 14 of the platform 1, respectively. Further, the first clamp mechanism 21 and the second clamp mechanism 22 can simultaneously clockwise rotate about the platform 1 in a direction from the first side surface 11 to the second side surface 12 (with reference to FIG. 4) under the action of driving mechanism 23. The first clamp mechanism 21 and the second clamp mechanism 22 are configured to clamp both ends of the roller 5 and accordingly can clockwise rotate the roller 5 about the platform 1 in the direction from the first side surface 11 to the second side surface 12 (with reference to FIG. 4).

(17) It should be noted, in this embodiment, the third side surface 13 and the fourth side surface 14 are the other two outside surfaces in parallel with each other and perpendicular to the horizontal plane, except for the first side surface 11 and the second side surface 12.

(18) In this embodiment, along the clockwise rotational direction (with reference to FIG. 4) of the roller 5 about the platform 1, the glue to be taken-up 3 and the cloth to be taken-up 4 are successively laid on the first side surface 11, and the glue to be taken-up 3 and the cloth to be taken-up 4 are also successively laid on second side surface 12. As such, when the roller 5 rotates clockwise about the platform 1, the glue to be taken-up 3 and the cloth to be taken-up 4 laid on the first side surface 11 or the second side surface 12 can be successively rolled onto the roller surface of the roller 5. As a result, the cloth/glue taking-up operation of roller 5 is finished.

(19) In this embodiment, the glue to be taken-up 3 and the cloth to be taken-up 4 are laid both on the first side surface 11 and the second side surface 12. Compared to the traditional cloth taking-up equipment, the cloth taking-up device according to this embodiment can roll the glue to be taken-up 3 and the cloth to be taken-up 4 on the first side surface 11 and the second side surface 12 onto different two rollers 5, improving the cloth taking-up efficiency of the cloth taking-up device.

(20) It should be noted that, the first clamp mechanism 21 and the second clamp mechanism 22 can also simultaneously counter-clockwise rotate about the platform 1 in a direction from the second side surface 12 to the first side surface 11 (with reference to FIG. 4) under the action of driving mechanism 23, such that the roller 5 can counter-clockwise rotate about the platform 1 in the direction from the second side surface 12 to the first side surface 11. In this case, along the counter-clockwise rotational direction (with reference to FIG. 4) of the roller 5 about the platform 1, the glue to be taken-up 3 and the cloth to be taken-up 4 are successively laid on the first side surface 11, and the glue to be taken-up 3 and the cloth to be taken-up 4 are also successively laid on second side surface 12. As such, when the roller 5 rotates counter-clockwise about the platform 1, the glue to be taken-up 3 and the cloth to be taken-up 4 laid on the first side surface 11 or the second side surface 12 can be successively rolled onto the roller surface of the roller 5. As a result, the cloth/glue taking-up operation of roller 5 is finished.

(21) In the invention, n pairs of first clamp mechanism 21 and second clamp mechanism 22 may be provided, wherein n2, and n is an integer. That is to say, the cloth taking-up device according to the invention may finish the cloth/glue taking-up operation of n rollers 5 at one time. The more pairs of first clamp mechanism 21 and second clamp mechanism 22 are provided, the better taking-up efficiency of the cloth taking-up device is, thereby greatly improving operation rate and productivity of the rubbing process. In this embodiment, as shown in FIG. 3, four pairs of first clamp mechanism 21 and second clamp mechanism 22 are provided.

(22) In this embodiment, the first clamp mechanism 21 may include a first clamp component 211 and a first retractable component 212 which are mutually connected, and the second clamp mechanism 22 may include a second clamp component 221 and a second retractable component 222 which are mutually connected. The first clamp component 211 and the second clamp component 221 are configured to clamp both ends of the roller 5; each of the first retractable component 212 and the second retractable component 222 can be extendable and retractable in a direction perpendicular to the first side surface 11 and the second side surface 12, such that the roller 5 moves far away from the first side surface 11 and the second side surface 12 or comes into contact with the glue to be taken-up 3 and the cloth to be taken-up 4 laid on the first side surface 11 and the second side surface 12. In the process of taking up glue and cloth by the rollers, when the first clamp component 211 and the second clamp component 221 with the rollers 5 clamped rotate to a position right above an edge of the glue to be taken-up 3/cloth to be taken-up 4, the first retractable component 212 and the second retractable component 222 are retracted, such that the roller surfaces of the rollers 5 come into contact with surfaces of the glue to be taken-up 3 and the cloth to be taken-up 4. The rollers 5 start the cloth/glue taking-up operation. When the glue to be taken-up 3 and the cloth to be taken-up 4 are successively rolled onto the rollers 5 with the rotation of the rollers 5, the first retractable component 212 and the second retractable component 222 are extended, such that the roller surfaces of roller 5 move away from the first side surface 11 and the second side surface 12. As a result, the cloth/glue taking-up operation of roller 5 is finished.

(23) In this embodiment, as shown in FIGS. 2 and 4, the driving mechanism 23 may include a first driving device 231 and a second driving device 232 which are disposed on the third side surface 13 and the fourth side surface 14, respectively. The first retractable component 212 is connected to the first driving device 231, and the second retractable component 222 is connected to the second driving device 232. The first driving device 231 and the second driving device 232 can drive the first retractable component 212 and the second retractable component 222 to rotate clockwise about the platform 1 in the direction from the first side surface 11 to the second side surface 12 (with reference to FIG. 4).

(24) In this embodiment, the cloth taking-up device may further include a first power source and a second power source (not shown). The first power source is configured to drive the first retractable component 212 and the second retractable component 222 to extend or retract, and the second power source is configured to drive the first driving device 231 and the second driving device 232 to rotate.

(25) In this embodiment, the first power source may be an air cylinder, and the second power source may be a motor. The air cylinder may drive the first retractable component 212 and the second retractable component 222 to extend or retract by compressed air. The rotation of the motor can drive the first driving device 231 and the second driving device 232 to clockwise rotate.

(26) In this embodiment, the cloth taking-up device may further include a vacuum adsorption part. The vacuum adsorption part may include a vacuum adsorption power source 26 and an adsorption plate 24. The adsorption plate 24 is disposed on the outside surfaces (in this embodiment, the first side surface 11 and the second side surface 12) of the platform 1 and connected to the vacuum adsorption power source 26 via a pipeline 25. The vacuum adsorption power source 26 can produce adsorptive force to keep the glue to be taken-up 3 and the cloth to be taken-up 4 on the adsorption plate 24. The adsorption plate 24 can keep the glue to be taken-up 3 and the cloth to be taken-up 4 flat, facilitating the cloth/glue taking-up operation of roller 5.

(27) In this embodiment, the adsorption plate 24 may include a vacuum adsorption felt or a vacuum adsorption sheet rubber. The vacuum adsorption felt or the vacuum adsorption sheet rubber can keep the glue to be taken-up and the cloth to be taken-up flat by uniformly distributed adsorptive force. Meanwhile, the vacuum adsorption felt or the vacuum adsorption sheet rubber may further have impact absorption property, assisting in cushioning the pressure of the rollers 5 when the rollers 5 come into contact with the surfaces of the glue to be taken-up 3/cloth to be taken-up 4. Therefore, the glue to be taken-up 3 and the cloth to be taken-up 4 may be more uniformly and smoothly rolled onto the roller surface of the rollers 5.

Second Embodiment

(28) This embodiment provides a cloth taking-up device. Difference between this embodiment and the first embodiment is in that, as shown in FIGS. 5 and 6, the first clamp mechanism 21 and the second clamp mechanism 22 are disposed on a bottom surface 15 and a top surface 16 of rectangular parallelepiped platform 1, respectively, which are parallel to each other and in parallel with the horizontal plane, rather than disposed on the vertical third side surface 13 and fourth side surface 14.

(29) Other structures of the cloth taking-up device according to the second embodiment are the same as that of the first embodiment, the description of which is omitted herein.

(30) The cloth taking-up device according to this embodiment also may possibly improve the uniformity of pressure applied to the glue to be taken-up 3 and the cloth to be taken-up 4 by the rollers 5, thereby further improving uniformity of taken-up glue/cloth and avoiding the cloth/glue dropped off situation; meanwhile, it is also possible to avoid foreign matters on the rollers 5 from dropping onto the glue to be taken-up 3 and the cloth to be taken-up 4 during the rotation, thereby further ensuring glue/cloth taking-up quality.

Third Embodiment

(31) This embodiment provides a cloth taking-up device. Difference between this embodiment and the first embodiment is in that, as shown in FIG. 7, one piece of glue to be taken-up 3 is laid on the first side surface 11, and one piece of cloth to be taken-up 4 is laid on the second side surface 12.

(32) In the cloth taking-up device according to this embodiment, only when the roller 5 clockwise rotates about the platform 1 by a round in the direction from the first side surface 11 to the second side surface 12 (with reference to FIG. 7), the cloth/glue taking-up operation of roller 5 is finished. The cloth taking-up device according to this embodiment is suitable to a case that areas of the first side surface 11 and the second side surface 12 are relatively small. Consequently, either the glue to be taken-up 3 or the cloth to be taken-up 4 is laid on the first side surface 11 and the second side surface 12.

(33) Other structures of the cloth taking-up device according to the third embodiment are the same as that of the first embodiment, the description of which is omitted herein.

Fourth Embodiment

(34) This embodiment provides a cloth taking-up device. Difference between this embodiment and the second embodiment is in that, as shown in FIG. 8, the platform 1 has a cubic shape and the glue to be taken-up 3 and the cloth to be taken-up 4 are laid on each of the first side surface 11, the second side surface 12, the third side surface 13 and the fourth side surface 14.

(35) Of course, either the glue to be taken-up 3 or the cloth to be taken-up 4 may be laid on the first side surface 11, the second side surface 12, the third side surface 13 and the fourth side surface 14, as required.

(36) Other structures of the cloth taking-up device according to this embodiment are the same as that of the second embodiment, the description of which is omitted herein.

(37) In the cloth taking-up device according to this embodiment, as long as four rollers 5 clockwise rotate about the platform 1 by a quarter round (with reference to FIG. 8), the glue to be taken-up 3 and the cloth to be taken-up 4 laid on the first side surface 11, the second side surface 12, the third side surface 13 and the fourth side surface 14 may be rolled onto the roller surface of the rollers 5. As such, four rollers 5 can simultaneously perform the glue/cloth taking-up operation, thereby greatly improving the cloth taking-up efficiency, and in turn greatly increasing the operation rate and productivity of the rubbing process.

(38) The first to fourth embodiments have the following advantages: in the cloth taking-up device according to the first to fourth embodiments, by laying the glue to be taken-up and the cloth to be taken-up on the outside surfaces of the platform having an included angle of 0-180 with respect to the horizontal plane and keeping the roller in parallel with the outside surfaces, the glue to be taken-up and the cloth to be taken-up can be rolled onto roller surfaces of the rollers in a lateral-press manner, whereby avoiding uneven pressure applied to the glue to be taken-up and the cloth to be taken-up by rollers in the case of taking up glue and cloth in the down-press manner, and in turn improving uniformity of taken-up glue/cloth. Meanwhile, cloth/glue dropped off situation may not occur in the finished rollers, thereby ensuring the rubbing quality of the rollers in a process of the rubbing formed alignment layer. In addition, since the glue to be taken-up and the cloth to be taken-up are situated in a non-horizontal position, the foreign matters on the glue to be taken-up and the cloth to be taken-up can easily fall off, and the foreign matters on the rollers cannot drop onto the glue to be taken-up and the cloth to be taken-up with the rotation, thereby ensuring glue/cloth taking-up quality.

(39) It should be noted that, for the purpose of simply understanding, in context, vertical side surfaces of the rectangular parallelepiped or cubic platform 1 are defined as the first side surface 11, the second side surface 12, the third side surface 13 and the fourth side surface 14, and horizontal side surfaces of the platform 1 are defined as the bottom surface 15 and the top surface 16. However, it should be understood that terms first, second . . . sixth used herein are merely intended to distinguish various side surfaces rather than constructed as limiting of the invention.

(40) In addition, it may be readily appreciated by those skilled in the art, the cloth taking-up device of the invention may be slantwise arranged in use. In the case where the cloth taking-up device is slantwise arranged, it is necessarily guaranteed that the first side surface 11, the second side surface 12, the third side surface 13 and/or the fourth side surface 14 on which the glue to be taken-up 3 and the cloth to be taken-up 4 are laid have an included angle of 0-180 with respect to the horizontal plane.

(41) It could be understood that the above implementations are merely exemplary implementations for the purpose of illustrating the principle of the present invention, and the present invention is not limited thereto. Various modifications and improvements can be made by a person having ordinary skill in the art without departing from the spirit and essence of the present invention. Accordingly, these modifications and improvements also fall into the protection scope of the present invention.
